Aliasing occurs primarily on assignment issues:The assignment to the base data type is simple. The base data type stores the actual numeric value, not the reference to an object, so when you assign it, you copy the contents of one place directly to the other. For example, if you use a=b for the base data type, then B copies the contents of a. and b is not affected by this modification at all.However, when the object is "assigned", the situation changes. When you manipulate an object, we actually

Paste (alias name): Javascript Regular Expression test webpageHow do you test regular expressions? Write the Code directly in a large segment, wait for the program to run there, and then use alert to display the result? Or is it possible to temporarily write a page and discard it after testing? You can try this page. Although it is rough, it is enough to test the regular expression :)) I. Description: 1. My intention is to exchange technology. I am

The full name of the class also becomes very long, and sometimes it is a waste of time. Today, I occasionally flipped through the book and found that using can actually define the class or namespace alias. For example: Using cryptns = realestate. Common. crypto; Using cryptmgt = realestate. Common. crypto. cryptomanagement; Class AA { Private void AAA () { // The two are the same implementations. Cryptns. cryptomanagement Mgt = new realestat
